WebThe Organic Rankine Cycle The ORC is a vapor power cycle that operates using the same principles as the steam Rankine cycle, except that a fluid with a lower boiling point (and higher molecular mass) is used. An organic working fluid is evaporated, instead of boiling water to create steam, to run through a turbine to generate electricity.
